I had a slightly similiar system with older bw speakers and onkyo sv90 125w receiver (MIT T2 IC's $50 each, Audioquest slate speaker cable $91). The onkyo blew away my denon 2801 that I bought. While looking at your system, your speaker cables sound much more expensive than what I think you need. I would have used the money on a decent 2 channel amp (anything around $200+) and bought a pair of under $80 used speaker cables later. I had audioquest slate which I bought for $90 from audioadvisor (they are much less than the oval 9 but yet are still a huge jump from zip cord). I now use MIT cables, which I think help with this type of equipment. The Denon's (and most surround receivers in general) are fine for watching movies, but as you can see from my previous posts to me there performance for music leaves something to be desired. I probably would have bought a nice integrated or pre-amp combo for the same money I spent on the Denon 2801 if I were to do it again. While having heard a similiar quality apex player via the digital out or analog coax the volume was very muted in comparison to my other DVD player, again I would not spend so much money on a digital cable for this $15-30 at most (canare digiflex, apogee wide eye, radioshack).
